Description

BACKGROUND OF THE INVENTION

The present invention relates to a component made of natural or synthetic stone for cladding protruding parts in the building field, for example the front part of the steps of a staircase.

Conventionally profiled elements are used for finishing the edges of steps and the like or for blending protruding parts of furnishings, said profiled being constituted by a contoured element which is provided, in a rear region, with means for anchoring to the element for cladding the structure that constitutes the horizontal surface and/or to the structure itself and blends the surface and the vertical surface of the step or other protruding part of furnishings.

However, these profiled elements, known as “stair trims”, suffer drawbacks, including the fact that they do not allow to obtain a uniform finish and a uniform color, since it is extremely difficult to obtain stair trims having the same shade of color as the parts to be finished.

Further conventional products for cladding the front part of steps and the like are constituted by a plurality of stacked tiles; in turn, these products require the use of pigmented bonding agents which must have the same color and shade as the tiles.

As an alternative, in order to obviate the above, these products can have, at the front edge of the stacked tiles, a contoured front which is glued to their exposed surface.

These products are in any case very heavy and expensive and require additional processes for facing the adjacent surfaces of the tiles; moreover, it is necessary to provide a cutout, or seat, on the front part of the structure that constitutes the horizontal surface of the step, in order to allow to position the product so as to avoid unaesthetic and dangerous differences in level.

The prior art also comprises products constituted by an upper tile which has, at the front and in a downward region, multiple portions of faced and stacked tiles which form a sort of finishing border for the protruding part.

In this case, with respect to products constituted by multiple stacked tiles, weight and size are partially reduced, but it is still necessary to carry out the additional operation of facing the surfaces that make mutual contact, in addition to the fact that the final thickness of the product is determined by the thicknesses of the stacked tile portions.

SUMMARY OF THE INVENTION

The aim of the present invention is to eliminate the above-noted drawbacks of conventional kinds of profiled element and product, providing a component made of natural or synthetic stone for cladding protruding parts in the building field, for example the front part of the steps of a staircase, which is variable in thickness and aesthetically valid, does not require the use of particular adhesives and pigments, is extremely compact and lightweight, and requires no additional operations for facing and forming cutouts and the like, as well as finishing elements.

Within the scope of this aim, an object of the present invention is to achieve the above aim with a structure which is simple, relatively easy to provide in practice, safe in use, effective in operation and relatively low in cost.

This aim and this object are both achieved by the present component made of natural or synthetic stone for cladding protruding parts in the building field, for example the front part of the steps of a staircase, characterized in that it comprises a tile which has, at its front edge, a first and a second strip which are respectively arranged at right angles and parallel to the tile, are mutually rigidly coupled and form a sort of a reversed L-shaped profiled element, the exposed surface of the profiled element being faced, fixing means being interposed in the interspace between the strips and the front edge portion of the tile.

DESCRIPTION OF THE PREFERRED EMBODIMENTS

With reference to the above figures, 1 generally designates a component made of natural or synthetic stone for cladding protruding parts in the building field, for example the front part of the steps of a staircase.

The component 1 comprises a tile 2 which has, at its front edge, a first strip 3 and a second strip 4 which are arranged respectively at right angles to the tile 2 and parallel thereto and form a sort of reversed L-shaped profile.

The strips 3 and 4 are rigidly fixed to the tile 2 , with interposed fixing means 5 in the interspace 6 formed by the internal surfaces of the strips and the front edge portion of the tile.

The exposed surface of the L-shaped profile is faced, by grinding, so as to form a sort of toroidal surface.

The profile and the tile are made of the same material and form eventually a single, monolithic body; advantageously, the strips are obtained directly from the tile by means of a cutting operation.

The first strip 3 is arranged so that its exposed surface 7 is in contact with the front edge of the tile 2 and so that its laying surface 8 is directed outwards and faced, as already mentioned, by grinding.

The means 5 for fixing the profile to the tile are constituted by adhesives and the like and determine the thickness of the component 1 ; conveniently, it is possible to insert in the interspace, in addition to the adhesives, wood or stone strips so as to be able to vary at will the thickness of the component to be manufactured and at the same time reduce the amount of adhesive to be introduced, thus reducing production costs.

The method for manufacturing the component 1 comprises a step for cutting the two strips 3 and 4 , a step for assembling the strips and placing them on the front edge portion of the tile 2 , a step for fixing the strips to the tile, and a step for facing the outer surface of the first strip 3 .

The cutting step ( FIG. 4 ) consists in cutting the tile 2 with a tile cutter in order to make it assume the chosen dimensions and thus obtain a first strip 3 and a second strip 4 .

The assembly and positioning step ( FIGS. 5 and 6 ) consists in joining the two strips 3 and 4 in a substantially right-angled arrangement so as to form an L-shaped profile and in arranging the resulting profile at the front edge of the tile 2 so that it faces backwards and so that the first strip 3 is perpendicular thereto.

In the first strip 3 , the exposed surface 7 is in contact with the second strip 4 and the laying surface 8 faces outwards.

The strips are assembled and arranged at the front edge of the tile by means of adapted systems for pressing the parts and by using quick bonding systems, such as adhesives which dry in a few seconds.

The fixing step ( FIG. 7 ) consists in filling the interspace 6 between the front edge portion of the tile 2 and the two strips 3 and 4 with fixing means 5 , such as adhesives and the like, which allow to obtain a monolithic body.

The facing step ( FIG. 7 ) uses conventional grinders which perform complete facing of the laying surface 8 of the first strip 3 and determine the toroidal shape of the profile.

In practice it has been observed that the above-described invention achieves the intended aim and object, i.e. to be aesthetically valid, to have a reduced weight and to be particularly adapted for cladding the front part of steps or the like, without requiring stair trims or additional blending profiled elements.

The invention thus conceived is susceptible of numerous modifications and variations, all of which are within the scope of the appended claims.

All the details may further be replaced with other technically equivalent ones.

In practice, the materials employed, as well as the shapes and the dimensions, may be any according to requirements without thereby abandoning the protective scope of the appended claims.
